论文以项目组合配置阶段界定为研究出发点,在分析项目组合配置多阶段过渡耦合模式的基础上,提出了以阶段内所有拟配置组件战略属性承载值加权和度量阶段内项目组合配置战略贴近度、紧前阶段释放对象有效利用率反映阶段过渡耦合度的分析方法,构建了基于阶段耦合的项目组合配置战略贴近度模型,并通过企业实践,对模型的可操作性进行了验证。 Based on the analysis of the multi-stage transitional coupling model of project portfolio allocation, this paper proposes a new strategy of project portfolio allocation strategy based on weighted sum of strategic attributes of all proposed components and the closeness of project portfolio allocation in the measurement phase, In the early stage, the effective utilization rate of the released objects reflects the transitional coupling degree of the stage analysis method, and a strategic closeness model of the project portfolio based on stage coupling is constructed. The feasibility of the model is verified through the practice of enterprises.
